The specific embodiment
Fig. 1 to 3 shows a kind of curtain airbag.This curtain airbag is made up of curtain type gas bag 10 and gas generator 40, and in the present embodiment, this gas generator is arranged on the side of curtain type gas bag 10.Curtain type gas bag 10 has air bag skin (Gassackhuelle) 12, and this air bag skin also is provided with two sidewalls 14,16 (referring to Fig. 3), interconnects by circumferential seam 20 in these two sidewall edge region 18.Air bag skin 12 is surrounded by air chamber 22, and this air chamber is divided into a protection zone 22a, leads chamber (Leitkammern) 22b and a filled chamber (Fuellkanal) 22c for two, and wherein, this filled chamber is at protection zone 22a and lead between the 22b of chamber.In the present embodiment, protection zone 22a is divided into a plurality of compartment 23a, 23b, 23c, 23d and 23e.In the 18a of top edge zone, be provided with first fixed equipment of a plurality of first fixed tabs, 30 forms, these fixed tabs are used for curtain type gas bag 10 is fixed on the inner structure of self-propelled vehicle.
Leading chamber 22b for two also is respectively equipped with and leads the chamber fixed equipment.In the present embodiment, these are led the chamber fixed equipment and constitute as follows: two sidewalls 14,16 are respectively equipped with through hole 24,26 in the zone of leading chamber 22b, and wherein, these two through holes are folded mutually to be provided with.Ring seal seam 27 (only shown in Fig. 1 a and 3) is extended around these two through holes 24,26.As shown in Figure 3, under fixing state, tingle 28, screw or like extend through two sidewalls 14,16 and also pass thus and lead chamber 22b, enter into the respective openings of interior of motor vehicles structure 50.
As shown in Figure 4, if at this moment air chamber 22 is inflated, leads chamber 22b and be divided into top 22b ' and bottom 22b thus ".Bottom between ornamental trimming 52 and interior of motor vehicles structure 50 is very accurately located, thereby produce desirable high processing safety.
As shown in Figure 1, the filling of leading the bottom, chamber appear at seam 27 around.
Install also very simply, like what can from the embodiment of Fig. 2, see, all fixed partss are located substantially on a height.
Fig. 5 shows the interchangeable embodiment of the present invention corresponding to Fig. 4.Here, be provided with another fixed tabs 32 as leading the chamber fixed equipment, this fixed tabs is stitched together at a side and sidewall 14,16 towards the interior of motor vehicles structure under assembled state.To this, realize through connecting seam 20a.Connect seam 20a on the transitional region of leading between chamber 22b and the filled chamber 22c.End away from connecting seam 20a of said another contact pin is provided with hole 34, and intermediate plate 28 or screw also extend through this hole, leads chamber 22b and locatees very accurately thereby also make at this.
Can know that like Fig. 8 connecting seam 20a is the part of circumferential seam 20, this connection is sewn in the transitional region of leading between chamber 22b and the filled chamber 22c extends, and here two sidewalls is interconnected.Therefore, fixedly seam not only is used for the fixing of another fixed tabs, but also is used to lead the separation piecemeal between chamber 22b and the filled chamber 22c.Identical with first embodiment, this connection piecemeal the function of leading the chamber is improved through two sidewalls 14,16.
The embodiment that adopts another fixed tabs location to lead the chamber especially has advantage under these circumstances; Promptly; For example be arranged on the air bag that is rolled into or is folded into a bundle like the Tab phenolphthaleinum chamber, shown in Fig. 6 and 7, wherein through one or more retainer belts 36; Fig. 6 is the scheme drawing corresponding to Fig. 2 form, and Fig. 7 is the section drawing along B-B line among Fig. 6.To this, another fixed tabs can be guided up or down.Accordingly, the fixed position of structural another fixed tabs of interior of motor vehicles will be arranged on be rolled onto or be folded together the protection zone 22a that forms a bundle above or below.
Can know that like accompanying drawing said curtain type gas bag is so to be arranged on the self-propelled vehicle, that is, the upper limb of curtain type gas bag is provided with downwards.This does not depend on that another fixed tabs upwards still is provided with downwards.
